field.cc:
BLOB variations have number-in-bytes limit,
unlike CHAR/VARCHAR which have number-of-characters limits.
A tinyblob column can store up to 255 bytes.
In the case of basic Latin letters (which use 1 byte per character)
we can store up to 255 characters in a tinyblob column.
When passing an utf8 tinyblob column as an argument into
a function (e.g. COALESCE) we need to reserve 3*255 bytes.
I.e. multiply length in bytes to mbcharlen for the character set.
Although in reality a tinyblob column can never be 3*255 bytes long,
we need to set max_length to multiply to make fix_length_and_dec()
of the function-caller (e.g. COALESCE) calculate the correct max_length
for the column being created.
ctype_utf8.result, ctype_utf8.test:
Adding test case.
No separate typecode for MEDIUMTEXT/LONGTEXT is added, as we
have no sound decision yet what typecodes and for what types are
sent by the server (aka what constitutes a distinct type in MySQL).
Added a test case for bug #10124.
sql_select.h, item_subselect.cc, sql_select.cc:
Fixed bug #10124.
The copy method of the store_key classes can return
STORE_KEY_OK=0, STORE_KEY_FATAL=1, STORE_KEY_CONV=2 now.
field.cc:
Fixed bug #10124.
When ussuing a warning the store methods return 2 instead of 1 now.
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable
adding test
field.cc:
bug#10714 Inserting double value into utf8 column crashes server:
sprintf was executed with too big length, which caused
crash on some Windows platforms.
Change string->float conversion to delay division as long as possible.
This gives us more exact integer->float conversion for numbers of type '123.45E+02' (Bug #7740)
Added auto-correct of field length for enum/set tables for ALTER TABLE
This is becasue of a bug in previous MySQL 4.1 versions where the length for enum/set was set incorrectly after ALTER TABLE
In server we assume that datetime values stored in MYSQL_TIME struct
are normalized (and year is not greater than 9999), so we should
perform range checks in all places then we convert something to
MYSQL_TIME.
"SHOW CREATE TABLE" mysql-4.0 and mysql-3.23
compatibiliry mode change:
Check that a binary collation adds 'binary'
suffix into a char() column definition in
mysql40 and mysql2323 modes. This allows
not to lose the column's case sensitivity
when loading the dump in pre-4.1 servers.
